QUOTE(weikee @ Oct 11 2011, 11:00 PM) Cheap woh. Did he dismantle the unit out and wash everything? My usual A/C service fellow will take out the indoor unit wash clean clean including the blower. Think his charges are above 100++ I use this for the indoor unit DIY Cleaning. Less dusty as the indoor unit is not dismantled. |

QUOTE(weikee @ Oct 11 2011, 11:40 PM) I watch the movie, the fin are so clean, comparing to mine is 100x cleaner, I try many diy cleaning but can't really remove all the dirt out. Got to remove the indoor unit out and fully flush out the dirt. The DIY may work if it clean like once a month or regular. Its more like once every year with the chemical for me. And I just spray water into the coils every couple weeks. Just don't get water into the electrical side (left side usually). |

QUOTE(ozak @ Oct 12 2011, 08:56 AM) I did try this DIY last few month ago. Took me half day to do it. The cleaning process is quite ok. But the blower side still not 100% clean. Cause the spray nozzle difficult to reach inside deep even it long and bend. For the price to buy the whole set and later on the chemical....eh...I think better get the service guy.  The trick is to get a hand held pump pressure spray and remove the entire plastic frame (remove 3 screws). Then you can get to most part of the coils and the spray pressure a lot better. Pretty easy once you get the hang of it |

QUOTE(ozak @ Oct 13 2011, 04:32 PM) I have this pressure pump for garden spray. I usually use to spray clean the aircon evaporator coil too. But the nozzle not long enough to reach the blower. Even open up the cover. Thats what I used to do previously except a full 110 bars of pressure onto the coil  Kind of messy with water all over the floor. Get a manual pressure sprayer (google for images). Gets everything off the evaporator coil. For the blower if its not terribly dirty a soft bristle brush will be able to get lots of the dirt off. Else mount a plastic bag (like the one in the DIY link earlier) and use the sprayer onto the blower. It works pretty well. Been doing the powered sprayer for over 5 years and this method more than a year now. A monthly cycle (15 mins) is all it takes to keep the evaporator coil clean. |
